There are several Indian IT consulting firms which have become giants that are known the world over. Infosys is one of these firms, and compared to its rivals it is better positioned in the consulting domain and growth verticals like retail and utilities. This means that Infosys' business model is focused on servicing marquee clients including JP Morgan, Bank of America, and Microsoft.
In comparison, rivals like Wipro and HCL have focused on and excelled in the areas of infrastructure management and product engineering services. These firms specialize in maintaining IT systems and helping their customers to realize efficiencies in their business processes, from reducing the number of parts in a car to reducing the weight of an aircraft. TCS is perhaps the biggest of all the Indian IT services firms, with a global footprint and revenues of $8.2 billion.
